49ers injury report: Ginn, Jacobs and (surprise) Demarcus Dobbs

It appears as if do-it-all Demarcus Dobbs won’t be doing much of anything.

At least for a few days.

Dobbs, 24, who has impressed this summer in his role as a defensive tackle and tight end, passed through the locker room this afternoon on crutches. His lower left leg was heavily wrapped and he was not placing any weight on his left foot.

With his ability to potentially serve as a No. 3 tight end, Dobbs could give the 49ers some roster flexibility as they prepare to trim down from 75 to 53 players Friday. He made the team as an undrafted free agent last year and was active for 12 regular-season games and both playoffs contests while playing defensive tackle.

I did not see Dobbs get injured during the 49ers’ 29-24 win over the Broncos on Saturday. He played both offense and defense and had one tackle for a loss. He was targeted once as a tight end, but the second-quarter pass was a throw-away by Alex Smith.

If Dobbs is sidelined for an extended period, it could open the door for Konrad Reuland to open the season as a third tight end. Reuland shares team-high honors with five catches and ranks third on the team with 51 receiving yards in three preseason games.

** Wide receiver Ted Ginn was wearing an orthopedic boot on his right foot in the locker room. Ginn left the field limping after he was tackled on an eight-yard reverse in Sunday’s game. Jim Harbaugh said X-rays were negative.

Ginn, who was exiting the locker room, didn’t respond when a reporter asked if he would be ready for the season opener at Green Bay on Sept. 9.

** Want some good injury news? OK, here’s a bit. Running back Brandon Jacobs is no longer using crutches after suffering a knee injury on Aug. 18 at Houtson.

Jacobs said he felt “absolutely phenomenal,” but he’s still walking with a pronounced limp.
